The super cars that could have been: Concept autos show past visions of the future from Ferrari, Porsche, Bugatti and others

A new exhibit shows off past visions of the future with concept cars from decades ago.

The 'Dream Cars' show at the High Museum of Art, in Atlanta, Georgia, features 18 cars from as far back as the 1930s to present day.

One-of-a-kind cars from automakers such as Ferrari, General Motors, Lancia, Bugatti, Porsche and more dot the museum floor.

Concept cars often capture the imagination of young and old alike. From Futuristic roadsters that eventually make their way into private collections to ideas that never saw the open road. They rarely enter mass production and often disappear after leaving the auto show circuit.

The display pairs conceptual drawings, patents and scale models with their finished products. It runs from May 21 to September 7.
